Here you go. 20 is like whispering.

80 Vacuum cleaner at 1 m (3 ft), curbside of busy street, PLVI of city
70 Busy traffic at 5 m (16 ft)
60 Office or restaurant inside
50 Quiet restaurant inside
40 Residential area at night
30 Theatre, no talking
20 Whispering
10 Human breathing at 3 m (10 ft)
0 Threshold of human hearing (with healthy ears); sound of a mosquito flying 3 m (10 ft) away

20 is pretty good for a fan
